How Do I Make a Picture Smaller?

It's probably happened to you. Someone you know sends you a photo in an email, it takes forever to load, and then WHOA! That's why it took so long! When you look at the photo you realize you're just seeing the top corner of someone's head. This photo is huge! Why is it so big? Can you shrink it?

When this happens, it's because the photo has a high resolution and no limit on the physical size of the photo. The resolution of a photo is measured in megapixels, which is a measurement of how many pixels are in a square inch of the photo. Check out this article for a quick lesson on megapixels and cameras: What's the Difference Between JPEG and RAW? Generally, when you send a photo in an email, or open it in an editing program, the program will shrink the photo down to a more manageable viewing size. Sometimes though, when someone has a photo with a high megapixel count, they choose to send it in its actual size which is great when viewed on large screens, but quite overwhelming on anything else.

So how do you adjust this? The easiest way is to save it to your device. If, for example, you viewed the photo in the email of your smartphone, saving the photo and opening it in the phone's photo viewer will resize it to the proper level. The same is true if you save it to your computer. While some photo viewing programs won't automatically resize, most will. If you're look for recommendations, Apple's iPhoto for the Mac or Google's Picasa for the PC are both good, free programs that allow editing, resizing, organizing and even sharing of photos.

Practical Tip of the Day:
Not sure what size photo to send to someone? Here's a good rule of thumb: How will they be viewing the photo? If they'll be viewing it on a smartphone, send a smaller version; this will minimize how much of their data plan is used loading it while giving them good enough quality for their screen. If, on the other hand, they'll be saving it on their home computer to later edit or print, send as close to actual resolution as you can. Computer can handle larger files more easily, and a higher quality photo is easier to edit and saves more of details.
